Variety used for comparison: 'Snowden'
Summary: The plants of 'NY139' have an intermediate foliage type structure whereas it is leaf type for 'Snowden'. The main stems of 'NY139' are thinner and have stronger anthocyanin colouration than 'Snowden'. 'NY139' has a lighter green leaf colour than the reference variety. The lateral leaflet of 'NY139' has a narrowly ovate shape with an obtuse base whereas it is medium ovate shape with a cordate base for the reference variety. 'NY139' has an medium number of red-violet flowers of medium size whereas the reference variety has few small white flowers. The anthocyanin colouration of the peduncle and on the inner surface of the corolla of 'NY139' is stronger than the reference variety. The colouration of the tuber skin of 'NY139' is light beige whereas it is chamois for 'Snowden'.

Origin & Breeding History: The potato clone 'NY139', previously evaluated as Y18-9, resulted from a cross made in early 1998 at Cornell University between the chipping clones NY120 (female parent) and NY115 (male parent). Seed from this cross was first sown in 1999 and transplanted on Mount Pleasant, near Ithaca, New York. Traits that were used for selection were the ability to chip directly from 44F cold storage, freedom from internal and external physical defects, resistance to scab, resistance to the golden nematode, specific gravity, maturity, and yield.
Tests & Trials: Tests and trials occurred during the summer of 2007 in Rawdon, Quebec. Sixty plants of each variety were in trial.
